Is it illegal for someone to rape him and kill him?

Not breaking the law is self-defense. If you have a strong sense of justice, you are extremely indignant, or the other party raped your girlfriend or something, and you have the heart to kill, then I suggest you kill yourself with one knife, which is easy and concise. This will simply judge self-defense, not be questioned, and there will be no thorns in the trial. Hello, I'm good, hello everyone ~
